Abstract

The invention provides a duct type cooling fan and relates to the technical field of duct type cooling fans. The duct type cooling fan comprises a cooling cylinder; the upper end of the cooling cylinder communicates with an air guide pipe; the other end of the air guide pipe communicates with a suction fan; the surface of the suction fan is fixedly connected with the cooling cylinder; and the other end of the suction fan communicates with a pipeline. By starting the fan, the suction fan can be used for sucking air from the inside of the cooling cylinder by using the air guide pipe; a filter cylinder which is positioned inside the cooling cylinder and communicates with the air guide pipe is used for sucking air at the center of exchange blades; a conical air guide hopper positioned at the bottom end of the filter core is used for discharging the air which flows in via the bottom of a rotating disc into gaps among the exchange blades; the exchange blades made of metal are used for sucking cold air which is generated at the surface of an exchange pipe; a compressor and the exchange pipe cooperate with each other to realize cooling ; the contact area between the cold air and the air isincreased by utilizing the exchange blades, and thus air cooling is quickened; and the cooled air is sucked into the pipeline by virtue of the suction fan, thereby solving the problem about relatively poor cooling effect of the duct type cooling fan which needs to start high air speed when high temperature is generated due to high-speed running of a motor.

Description

technical field [0001] The invention relates to the technical field of ducted cooling fans, in particular to a ducted cooling fan. Background technique [0002] The ducted fan can generate greater wind force than the isolated fan of the same diameter, and the fan ring is enclosed in the duct, which can not only prevent the aerodynamic sound of the fan from spreading outward, but also has a compact structure and high safety. For refrigeration, a compression condensing pipe is often laid inside the duct. When the speed of the fan in the duct is increased, the airflow will pass through the duct quickly, and the contact time between the fast-flowing airflow and the condensation pipe will be shortened, and the high-speed flowing gas will Self-generating friction in motion generates heat, and the high speeds of the motor generate high temperatures, resulting in ineffective cooling when high-velocity airflow is required. [0003] Compared with the double-duct fan whose application...
